The Nikon 1 V1 is among the fastest autofocusing cameras and is a nice compact size with the option of interchangeable lenses. Features a 1" sensor (vs a 1/2.3" found in compacts or 4/3" found in most other mirrorless). It uses a discreet silent shutter and very good continuous shooting rates with image quality that compares well with other mirrorless cameras. The upgrades of the V1 over the less expensive J1 include an electronic viewfinder (worth the price difference alone) and higher resolution LCD display.
